Ciao to everyone!
First of all I wish introduce me.
I'm Francesco Alessi, and I'm the main developer of Arduino STAR OTTO. I have to say thanks to Roger for his work on maple, I started the development from his repo. I have also to say thanks to some ST guys, that supported (and still supporting) me during the development.
To reply to someone, not all of ST people know about OTTO, because this board is not a ST board (was developed with the support of ST), but is a pure Arduino.org board, designed, produced and developed in Italy
The code of OTTO is on the Arduino.org repository, in STM32F4 branch: https://github.com/arduino-org/Arduino/tree/stm32f4
I'm writing for two reason:
1) I wish to develop the code of OTTO with yours suggestion, because my idea is to have realy one board developed together, looking in the direction that you suggest, hoping to develop the code in the best way, and if you want with yours contributions.
2) If for you is a good idea, I will ask to my colleagues to open a specific section of Arduino Forum, to have an official place to gather all comments and suggestion (of course without leaving this beautiful place to discuss, which is a reference for all community of developers STM32). I wish to open the forum section because I'm able (I hope) to reply to your technical question, but not for other questions, and the forum is readed also from other guys that may know other answers.
I'm ready to reply to all of your questions!
Ciao to all!
